Collectible coins encompass a wide range of numismatic items, including historic, commemorative, and rare pieces. In the context of the United States, notable examples include the G 5 series coins and pieces produced by notable mints like A. Bechtler, who created gold coins in the early 19th century from his North Carolina mint. The 1922 date refers to various coins minted in that year, such as the highly sought-after 1922 Peace dollar, which commemorated the end of World War I and symbolized peace. Collectors often seek these coins for their historical significance, rarity, and aesthetic appeal.
